SHUTTLE-BOX-OPERATING DEVICE FOR LOOMS.

SPECIFICATION forming part of Letters Patent N0. 329,396, dated October27, 1885.

(No model.)

To all whmn it may concern.-

Be it known that I, LUcrUs J. KNOWLES, of \Vorcester, in the county ofIVorcester and State of Massachusetts, have invented certain new anduseful Improvements in Shuttle-Box- Operating Devices for Looms, and Ido hereby declare that the following is a full, clear, and exactdescription of the same, reference being had to the accompanyingdrawings,

IO forming a part of this specification, and in which Figure 1represents a vertical section through a loom-frame just in front of thelathe and shuttle-boxes, showing a side view of said 5 lathe andshuttle-boxes with my improvements applied thereto, as well as a sideview of the arch-stand or upper part of the loom-frame, as will behereinafter more fully described. Fig. 2 represents, upon an enlargedscale, a central vertical section through a portion of one of theshuttle-boxes and its lifter, taken on line a, Fig. 1, showing myimprovements applied to the same; and Fig. 3 represents, upon the sameenlarged scale as Fig. 2, a vertical see tion through a portion of thelathe and one of the shuttleboxes, showing a side view of myimprovements, the lifter'rod being shown by full lines attached to theshuttle-boxes and by dotted lines detached from the same, as will behereinafter more fully described.

My invention consists in the combination of the shuttle-boxes and alifter having laterallyprojecting arms for supporting said shuttleboXeswith the lifter-rod, a flange formed upon 3 5 or secured to the bottomof the shuttle-boxes provided with a horizontal opening, and a screw orstud fastened to the upper end of the lifter-rod upon a line with theopening in the aforesaid flange and adapted to be inserted to into saidopening, as and for the purpose hereinafter described.

To enable those skilled in the art to which my invention belongs to makeand use the same, I will proceed to describe it more in 4 5 detail.

In the drawings I have represented so much of an ordinary loom as isnecessary to show the nature and advantages of my improvements.

The parts marked A represent the framework of the loom; B, the lathe; C,the handrail; D, the lay-swords; E, the shuttle-boxes, which arearranged and operate upon the parts F of the lathe B; G, the shuttle-boxlifters; H, the lifter-rods; I, the 1ifter-rod springs; J, thelifter-rod tubes; K, the rockerirons, and Lthe protector-rod upon whichthe protection-fingers L are secured for bearing upon theshuttle-binders M, and daggers N for stopping the loom when the shuttlesare in 6 any way retarded or stopped during the operation of weaving.The shuttle-box lifters G are raised and lowered with the lifter-rods Hby means of the dropbox levers of the loom, said levers being connectedwith the tubes J upon the lifter-rods by means of connectingrods 1) andchains 0. The latter work on wheels or trucks d, supported by theframe-work of the loom. If desired, a better understanding of theoperation of said drop-box levers may 7( be obtained by reference to thePatent No. 134,992, granted to me January 21, 1873, for improvements inlooms. The bottoms of the shuttle-boxes rest upon the outer ends of thelifter-arms 9, formed upon or secured to the lifters G,which latter arein turn formed upon or secured to the upper ends of the lifter-rods H.Therefore,when said lifter-rods and lifters G are raised by the drop-boxlevers, as aforesaid, the shuttle-boxes are also raised, and when thelifter-rods and lifters are lowered said sh uttle-boXes follow, owing totheir weight and to their being attached to the upper ends of thelifter-rods, as hereinafter described. The shuttle-boxes are arranged toslide up and down in suitable ways, h, made in the parts F of the lathe.They are attached to the upper ends of the lifter-rods, as beforestated, in the following manner: Upon the bottom of each shuttle-box, ator near its cen- 9o ter, is formed or secured a flange, 6, having ahorizontal opening through the same, into which maybe inserteda screw orstud, f, fastened in the upper end of each lifter-rod H upon a line withsaid opening.

Said screws or studs are fitted loosely in said openings, and made ofjust sufflcient length to extend through the flanges e, as shown in Figs2 and 3 of the drawings.

By employing a fastening such as above described for attaching theshuttle-boxes to the lifter-rods I am enabled to remove saidshuttleboxes, when required for renewal, repairing, or wiping the same,in a very convenient and expeditious manner by simply springing back thelifter-rods and parts attached thereto, as shown by dotted lines in Fig.3, so as to wit-hdraw the screws or studs from the openings in theflanges 6, when the shuttle-boxes may then be easily taken out. Inperforming said operation the attendant in practice, while springingback the parts, as before described, with one hand, removes theshuttle-box with the other. As the lifter-rods are of considerablelength, and held (when detached from the shuttle-boxes) only at theirlower ends, they may be easily sprung at their upper ends to obtain theresult above described. The

openings in the bottoms of the parts F of the lathe through which theypass are also made of sufficient size to admit of said springing motion.

It will be understood that when the lifterrods are in their normalpositions with the screws or studs f in the openings 6, as shown by fulllines in the drawings, they are held with sufficient firmness andrigidity to securely hold the parts together, and cannot becomedisengaged,except by springing the lifter-rods back by force, as beforedescribed. Therefore it will be seen that my improved fastening, whileadmitting of the easy removal of the shuttle-boxes, also holds saidshuttle'boxes in a secure manner against a rocking or wabbling motion,owing to the construction before de-' scribed, and may be operated upand down with as little friction as when rigidly or otherwise fastenedto the lifter-rod.

The other portions of the loom shown in the drawings, being of old andwell-known construction, require no further description.

Having described my improvements in shuttle-box-operating devices forlooms, what I claim therein as new and of my invention, and desire tosecure by Letters Patent, is-

The combination, with the shuttle-boxes E and lifter G, having arms 9,of lifter-rod H, pinf, and flange e, substantially as shown anddescribed, for the purpose stated.
